With the rapid development of China’s national economy, the comprehensive utilization of mineral resources and its industry develop rapidly. The material crushing is an indispensable process in the production in many industries (such as metallurgy, mining, building materials, chemicals, ceramics, road construction, etc.). In order to meet the requirements of a variety of materials, due to the physical properties of materials and structural differences, the mining machinery enterprises should produce different types of crushers. For the metal ore beneficiation, crushing is the first process of the concentrator. In order to separate the useful minerals, the crushing process can be divided into rough crushing, medium crushing and fine crushing. Since the crushing process consumes large amount of energy in the concentrator (about 50% of the power consumption of the whole plant), in order to save energy and improve production efficiency, the crusher develops towards energy-efficient direction of the fine crushing, grinding.

Generally speaking, the common jaw crusher is usually used for coarse crushing which is the preparation work for milling. Fine jaw crusher emerges according to production requirements. It is widely used in small mine, building material, road building, silicate and chemical industry. The to-be-crushed material is usually the rock or ore with granularity less than 210mm and compression strength less than 250 kilo/square centimeter.

Fine jaw crusher is similar to coarse jaw crusher due to their same motor composing of rack, movable jaw, eccentric shaft and fixed jaw plate, mobile jaw plate and adjustable seat. The to-be- crushed material in crushing chamber is crushed by reciprocal motion of movable jaw plate caused by eccentric shaft driven by triangle belt through scored pulley. The crushed material is discharged from the discharging port by virtue of gravity.

Bracket plays an important role in supporting movable jaw. Except for that, it also has insurance effects on the movable jaw when exotic material enters the crushing chamber.

Adjustable seat can move forward and backward around sliding slot on the two sides of rack. There is a pair of adjustable gaskets between adjustable seat and rack. After the adjustable seat is adjusted, the required granularity of products can be gained when the width of discharging port and the thickness of gaskets are changed.

In chemical industry, coarse crushing is mainly used in building industry. Thus, the cover area of application will be gradually larger because the fine crushing and coarse crushing are mutually complementary.

The structure factors of jaw crusher refer to structure parameters of crushing chamber. The crushing chamber has a decisive influence on the product granularity in stable operating performance. The length of parallel area and the size of closed discharging mouth are designed by the customers” demand of product granularity, which plays a key role in the productivity of jaw crusher. The length of parallel area is longer and the size of closed discharging mouth is smaller, and which can improve the product granularity but cause productivity dip; otherwise the productivity of jaw crusher can improve. Therefore, using the optimal length of parallel area and the suitable width of closed discharging mouth is very important in the certain parameters of operating performance.
